Running Light Reflective Gear, Bright Waterproof LED Safety Light with Red Taillights, USB Rechargeable 500 Lumens, Elastic Adjustable Strap with High Visibility for Night Runners Jogging Dog Walking

Didn't make it past the first charge. The usb micro charging port is weakly attached to the board with a couple of solder links. They didn't survive plugging in a usb b cable. I tried to resolder it, but couldn't get a good link. Utter garbage.I used it for a 30K run on a full charge that it had upon arrival. Was okay. Odd, keyhole shaped pattern. Bright enough to run. Can't survive the whole night on a full beam, but it is nice as a backup when you tire of wearing your headlamp. I think about 4 hours. It starts to fade gradually before it goes dead.Obviously can't charge it once the port breaks off, which seems inevitable.I cannibalized mine, using the led, housing and straps, which are okay. Directly connect to a portable usb power supply, but I wish I didn't buy this piece of landfill in the first place.

I run in the morning before dawn. This light works great. It's too bright for me on high, so I set it on low brightness. It's still plenty bright to see where I'm going on roads, even on trails. On the lower brightness setting, I think you could get 15-20 runs in before needing to charge. I haven't had to charge mine yet. Very happy.

Works at -2 degrees. Fits over heavy coat and is super bright. Only need to recharge once a week when using it for 40 minutes each night walking the dog. I live in a rural suburb with no street lights. This allows me hands free access to the leash. It is water resistant as have used it in poring rain and blizzard conditions. Buy it. It has saved me from being hit by a car more than once.

This was an excellent option to provide light while I jog during early morning hours. The front light is brilliant! Cars and other joggers/walkers can spot me far enough away to alert them to my presence. Attaching the harness to my body is ackward...but it works fine. Would have preferred a more conventional vest option. Good value for money.

I've only used it a few times, for maybe about 4 hours of jogging. The throw of the light does shift side to side with each stride, but doesn't have much vertical bounce at all. I'm a medium build guy and it fits well.
